Abstract

Different from the conventional energy transmission which uses air-core coil as a carrier , This paper mostly discusses the effect of energy transmission efficiency with core added; this paper also discusses the receiving terminal signal virtual value variation of hysteresis loop of the core material with a sine wave signal fixed to the power input terminal, aimed to compare and analyze the effect of wireless energy transfer efficiency between air-core coil and iron-core coil. Through theoretical analysis and experimental data, it shows that the efficiency of energy transmission can be effectively improved by adding iron core.
